Cable sleeve sealing assembly

Abstract

A sealing assembly particularly for cables including an essentially tubular slotted casing formed of thermally shrinkable material having a pair of longitudinal edges with protuberant fastening elements extending in a direction generally longitudinally of said slotted casing being provided adjacent each of said longitudinal edges. A clamping element preferably of a C-shaped configuration is provided for holding together the longitudinal edges of the slotted casing. The clamping element is loosely engaged on the fastening elements in the assembly position thereof and rigidly clamped thereon in the operative condition of the assembly.

What is claimed is: 
     
       1. An assembly encasing in a sealed arrangement an item such as a cable or the like comprising: an essentially tubular slotted casing consisting essentially of thermally shrinkable material having a pair of longitudinal edges;   said casing being shrunk by application of heat thereto to encase in sealing engagement therein said item;   first and second fastening means extending longitudinally of said casing alongside each of said longitudinal edges, respectively; and   a tubular annular slotted clamping element arranged with a pair of longitudinal clamping edges engaging therebetween both said first and second fastening means to hold said fastening means together during formation of said assembly;   said clamping element being encased within said casing thereby to enhance the clamping effect of said clamping element upon said fastening means by the action thereon of said heat shrunk casing.   
     
     
       2. An assembly according to claim 1 wherein said clamping element comprises a longitudinally slotted clamping tube made of rust proof material. 
     
     
       3. An assembly according to claim 1 wherein in the position of operation of said assembly said clamping element projects beyond said casing at both ends thereof. 
     
     
       4. An assembly according to claim 1 wherein said first and second fastening means comprise a pair of bulges formed integrally in said slotted casing adjacent the edges thereof, said bulges having different sizes with one of said bulges being smaller and the other being larger and with said smaller bulge being engaged with a snap fit in said larger bulge when said longitudinal edges of said slotted casing are connected together. 
     
     
       5. An assembly according to claim 4 further comprising a support element arranged within said smaller of said bulges. 
     
     
       6. An assembly according to claim 5 wherein said clamping edges define a gap therebetween and wherein said support element is circular and has a diameter greater than the width of said gap. 
     
     
       7. An assembly according to claim 4 wherein said smaller bulge is formed as a plurality of bulges arranged to extend parallel to each other. 
     
     
       8. An assembly according to claim 1 wherein said clamping element is formed with a C-shaped configuration.
